Now, many primary schools and middle schools are recycling textbooks. In my opinion, it’s necessary.
As you know, save paper means save trees and money. Trees also have many advantages, like: to produce oxygen, control the climate. Some trees can produce rubber or medicine etc. Trees are a kind of natural resources. We must protect them.
To print books. We must use a lot of time and people. We have to use electricity and water. In China water is ‘rare’. So we must save it! Save water is everybody’s responsibility.
In a word. I agree with recycle textbooks and I hope we can do this forever
